Update libavb to commit 5fbb42a189aa in AOSP/master, because new version
has support for super partition [1], which we need for implementing
Android dynamic partitions. All changes from previous patches for libavb
in U-Boot are accounted for in this commit:
- commit ecc6f6bea6a2 ("libavb: Handle wrong hashtree_error_mode in
avb_append_options()")
- commit 897a1d947e7e ("libavb: Update SPDX tag style")
- commit d8f9d2af96b3 ("avb2.0: add Android Verified Boot 2.0 library")
Tested on X15:
## Android Verified Boot 2.0 version 1.1.0
read_is_device_unlocked not supported yet
read_rollback_index not supported yet
read_is_device_unlocked not supported yet
Verification passed successfully
AVB verification OK.
Unit test passes:
$ ./test/py/test.py --bd sandbox --build -k test_avb
test/py/tests/test_android/test_avb.py ss..s.
